-Combiner Source
----------------
-
-To utilize the combiner source, the `pkgbase` section must be declared as the
-combiner source. Additionally, individual sections should be added using a
-quoted table key consisting of the `pkgbase` followed by the stage name,
-separated by double colons. For example: `["sudo:stage1"]`.
-
-This allows to chain different sources together into one result, or allow
-multi stage transformation of our source via multiple regex.
